Problem Resolution
Login Failed. Only one client allowed. One
client session is active or has not yet timed out. If you closed the client using Windows Task Manager (End Task or Process) or using Unix
process ID (kill command), successful relaunch of the application may take up to 2
minutes.
Problem Resolution
Management server exits
unexpectedly on Red hat
Linux 6.1 A possible cause is low swap space configured on the system. As per the standard recommendation, swap
should equal 2 times physical RAM for up to 2 GB of physical RAM, and then an additional 1 times physical RAM
for any amount above 2 GB, but never less than 32 MB.
Therefore, if M = Amount of RAM in GB and S = Amount of swap in GB, then
If M < 2
S = M *2
Else
S = M + 2
